-1 Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).
Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:
20
+
5
=
25
So the second play they get sacked deep and lose 6 yards. So we subtract 6:
25
−
6
=
19
So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:
19
−
20
=
−
1
and this makes sense because we know we advanced 5 and fell back 6

How do you convert a mixed number into a improper fraction

Llana [10]

To convert a mixed number into an improper fraction, you can multiply the denominator of the fraction by the whole number. Then, you add the product with the numerator to get the new numerator. The denominator remains the same.

Answer:

The correct answer is 31x + 0.5

Step-by-step explanation:

∵ 13x + 5 + 17x - 4.5 + x

To solve this correctly you must to add the coefficients of the like terms (terms who has same variables or constant terms)

∵ 13x , 17x , x are like terms ⇒ terms with same variable

(same letters and same power)

∵ 5 , 4.5 are like terms ⇒ constant terms (numbers only)

∴ (13x + 17x + x) + (5 - 4.5) = 31x + 0.5

* The error of first answer:

- 18x + 17x - 4.5 + x

- She add 13x + 5 = 18x ⇒ she add unlike terms

* The error of second answer:

- 35x - 4.5 + x

- She add 13x + 5 + 17x = 35x ⇒ she add 2 like terms with 1 unlike term

* The error of third answer:

- 30.5x + x

- She add 13x + 5 + 17x - 4.5 = (13x + 17x) + (5 - 4.5) =

30x + 0.5 ⇒ she add 2 like terms and 2 constant terms

and then add the 2 unlike answers

* The error of fourth answer:

- 31.5x

- She add 13x + 5 + 17x - 4.5 + x = (13x + 17x + x) + (5 - 4.5) =

31x + 0.5 ⇒ she add 3 like terms and 2 constant terms

and then add the 2 unlike answers
